hi there

probably my house will be in the water and my small cooling pool will be under the water in the coming days.  now last minute preparation, what should I do with it ?

a) keep water, then drain the flood water later ?

drain water now, then it is faster to drain the dirty flood water later ?

c) pump and chlorinator program álready shut down and unplug

d) close all valves, or leave them as they are now ?

e) return to serve tank, block it or leave it ?


any idea would be helpful !



cheers

Leave it, shut of all power sources to it and before restart make sure you dry out the equipment thoroughly and use a water dispersant like WD40 or something. Definitely do not drain it, it will pop out of the ground there's not even much guarantee it won't come up a bit anyways, but in this situation there's not much you can do, just clean it out after the floods is really all there is..
And good luck..

Interesting (conflicting) advice...............

Think about it mate, what is the worst thing that could happen? The pool lifting. Flood water is unpredictable and an empty pool is highly vulnerable. Which brings me on to pool construction....

With all the problems of flooding in Thailand, which is fast becoming the norm here, perhaps it is time to consider more appropriate pool designs. The high water tables here is another cause for concern and there is a solution that addresses both these problems, a "half in, half out" pool.

Using the water table as a datum, install a substantial concrete sub-base and construct the pool on that. If the top of the pool is a metre above ground, dirty floodwater is unlikely to damage it, unless you are very unlucky and very low lying.

In the case of a concrete pool, "pool lifting" is no longer a danger when draining the pool, so no need for those troublesome hydrostatic valves. The pump can be installed at ground level too, without fear of flowback and the pipework greatly simplified.

If your house is raised to combat flooding problems, as many are in Thailand, build the pool on the same level as the house, as I am.

Depending on how high you expect the water too go?
You may need to unplug and take away pumps Salt chlorinator and anything else electrical.
Other wise they will be stuffed and no warranty.
Leave the water in the pool.
Once the flood water recedes you can look at how to clean the water then.
Best bet will be
High dose of 90% chlorine and let settle for a couple of day.
You may also need to floculate as well.
After it has settled (Day or two)
Vacuum to waste and top up with clean water.
If it is a salt pool you will then need to top up with salt.
PM me if you need more help.

Good luck

^No chance to save that crap water once it's flooded, I know from first hand personal experience. Just drain it several weeks afterwards, remove the bottom plug if there is one, clean and refill. It's a small cooling pool guys not a "swimming pool" in that context, even still it's a complete waste of time and money to even consider trying to re-balance the swamp water that is flooding this region if his pool gets flooded..

Allan none of that is necessary I've been working with/building pools in an environment similar to this with constantly high subterranean water table for 25 years and nothing so drastic need to be done. An experienced and qualified pool tech will have no problems with the water table here or anywhere for that matter, but prior consideration in building is important.

Anyways where is the conflicting advice? and BTW his pool is already built..

thanks for all the inputs . . . and my small 'cooling pool' already been flooded.

two causes :
1) the pool edge is 40cm above ground, but the flood is 60cm :-(  
2) forgot to block the return to the serve tank, then it also been flooded.

we left the house in a rush.  I shut down the power to the pump and to the chlorinator. just back after evacuated 4 weeks and 2 days. I don't want to describe the condition of the water :-(

I just bought a drop-in pump from HomePro, and try to drain the dirty water and by pass the pool pump. it is just the 2nd big cleaning day :-)
